FIELD

The retractable top for an open vehicle relates to a convertible top for modern Jeeps® or other vehicles with a passenger compartment and an open rear compartment.

BACKGROUND

Retractable tops for Jeeps® exist in the art; however, current designs are somewhat limited and do not fit current Jeeps and other vehicles. No design exists that accommodates a left and a right roll bar that connects from a side panel forward to the central roof roll bar, referred to as a roll cage. The new roll cage configuration of more modern Jeeps provides less space as compared to previous Jeeps for the mounting of a retractable top. Jeep does not currently make a retractable top and its designs are not made to accommodate one.

SUMMARY

In one embodiment, the top accommodates a pair of right angle roll bars, which extend to the rear of the floor of the open rear compartment and extend straight upward from the floor on the left and right rear sections of the vehicle, and then go forward to the central roof roll bar, referred to as a roll cage. Models 1989-2010 T-J, K-J, Y-J Jeep Wranglers® and 1976-1988 C-J7 Jeep Wranglers® are expressly provided for, wherein previous designs will not fit these models. Furthermore, in another embodiment, the retractable top is configured to attach to the side of the vehicle frame as opposed to the floor or wheel wells. In another alternative, the top incorporates a bow arm having recessed apertures for receiving attachment member, such as a bolt or clamp, in order to allow attached bow arms to rotate close to the first arm without being impeded by an attachment member end. In other alternatives, the bow also includes a stop to prevent the pinching of enclosure material. Other alternatives, include an optional electric motor actuator, a powered rear bow to help lift the top material, a motor stop, a free wheeling motor to allow a wind to force the top down from a partially open position or to allow a manual operation, a secure wind-resistant closure for the vertical door brackets, a boot for the door brackets, an easy-acting windshield clamp, a tightening cable and anti-jam cable in the linkage, and rubber seals for the windshield and door joints. Other alternatives include a folding mode, which does not require an extension backward of the spare tire assembly, and a detachable rear window.

DETAILED DESCRIPTION

Currently, Jeeps® are not designed to be fitted with a retractable top. In fact, a number of features of Jeeps, especially those made in more recent years make the fitting of a top to a Jeep more difficult. Since Jeep has moved from a roll bar to a roll cage to protect rear passengers, a retractable top must traverse the approximately right angle of the roll bar. Also, the roll cage makes the available mounting area for a retractable top extremely narrow, since the top must be on the outside of the roll cage. The location of the roll cage and configuration of the Jeep also makes attachment to the floor of the vehicle extremely difficult in recent model. Furthermore, it is difficult to form an airtight seal on the side of the Jeep. These challenges are found with other open compartment vehicles, such as the Hummer H1 and other open compartment vehicles. Embodiments of the retractable top described herein include innovations that allow for a narrow profile to the retractable top, the traverse of a sharp angle of the roll cage, the side mounting of the retractable top, the windproof fit of the side panel, and numerous other innovations. Although these innovations are described in relation to a Jeep vehicle, they can be similarly provided to open compartment vehicles.

For instance, in order to narrow the profile of the linkage arm configuration, tapered slots are used for receiving some of the attachment mechanisms (bolts) used. This is primarily in relation to the second bow arm (also referred to as the second linkage arm). Since the second bow arm attaches to multiple other arms, it would not be possible to fit the arms closely together and still provide for the proper rotation of the arms. By using a tapered receiving slot, the attachment mechanism used is set into the second bow arm and therefore does not project away from its surface. Therefore, the face of the second bow arm and other arms attached to it may be closer while still allowing for a greater degree of angular rotation needed to fold and unfold the retractable top. Also, in some embodiments the rubberized top is made of stay-fast an extremely flexible cloth-like material. This material, stay-fast, enables fluid operation of the top in some embodiments due to its high degree of flexibility. In some embodiments, extremely flexible top material is needed.

Additional detail may be found below describing various embodiment configured to fit with Jeeps that include a roll cage. The principles of these embodiments may apply to various other vehicles with such an open compartment and roll cage configuration. In some alternatives, the various metal arms are referred to linkages, in other instances bows or arms. These terms will be understandable and interchangeable to those skilled in the art and will recognize their interchangeable nature.

Referring first to FIGS. 1 and 2, a first embodiment retractable top 1 is seen to have a pair of horizontal support plates 2 preferably designed to mount atop a pair of rear wheel wells in the rear compartment of various Jeeps®. Although the embodiment is shown as being mounted on a Jeep®, the top may be mounted and reconfigured for a variety of vehicles having an open rear compartment or an open front and rear compartment. A pair of vertical linkage support brackets 3 each have a foot 4 attached to the support plates 2. Bolts (not shown) mounted through holes 5 secure the support plates 2 to the vehicle. A parallel vertical trailing arm motor plate 38 supports pivot mount 14. The vertical linkage support brackets form a means for attaching the top to the vehicle. The vertical linkage support brackets may also be termed “support members” and may come in various forms not limited to the embodiment shown. Various brackets, plates, and other structures may be used to attach the top to the vehicle.

A two-directional motor 7 has a drive gear 71 supported by the support bracket 3, wherein gear 71 drives a linkage gear 8 which is fastened to the first linkage arm 9. The center of linkage gear 8 has an axle 10 which supports first linkage arm 9 in a pivot mount so that first linkage arm 9 can be moved from the fully deployed position shown to the retracted position shown in FIG. 3. A rear bow 11 has a pivot mount 12 so as to fold parallel to the first linkage arm 9 in the retracted position shown in FIG. 3. However, a stop (not shown) stops the bow 11 from moving more than angle a, thereby causing bow 11 to lift and support the top 80 as shown in FIG. 8. Top 80 can be any flexible material such as canvas, cloth, or other material.

A second linkage arm 13 has a pivot mount 14 on the trailing arm motor plate 38. The upper end of second linkage arm 13 has a pivot mount 15 to third linkage arm 16, which is also pivot mounted at 17 to first linkage arm 9, and has pivot mount 36 to linkage arm 20. A fourth linkage arm 18 has a pivot mount 19 to fifth linkage arm 20 which has a rear end pivot mounted to the top of the first linkage arm 9. A sixth linkage arm 21 has a pivot mount at a forward end to frame 22 at 23 and a pivot mount 24 to fourth linkage arm 18. These linkage arms form a means for supporting the retractable top of the vehicle, although other pieces shown in the figures may be included in the supporting means. Further, arrangements that depart from the embodiment shown are possible. The support means is configured to cover the top of the vehicle, while keeping the amount of overlap and protrusion at a low level. The support means is also designed to fold for storage as shown in FIG. 9.

A mid bow 25, supported by brackets 37, has a fixed mount bracket 26 to the fifth linkage arm 20. A support rod 27 adds structural rigidity between the two brackets 26. A front bow 28 has a pivoting bracket 29 mounted to pivot mount 24. A support rod 30 adds structural rigidity between the two brackets 29. The front frame member 31 has windshield clamps 32. During transition, the third linkage arm 16 continues to move essentially parallel to the ground.

In FIG. 1, the offset steel brackets 33 can be seen extending forward as they are pivot mounted at 34 to first linkage arm 9.

In FIG. 2, the stop 35 is shown midway to flange 36, which prevents the motor 7 from over deploying the top 1. The motor 7 is a free-wheel type to allow manual deployment of the top 1 as well as to allow a strong wind to retract the top 1 when the driver turns the motor 7 off. K-arm control spacer 39 supports linkage arm 18.

Referring next to FIGS. 4, 5, and 6, a second embodiment top 100 is shown in the same sequence of views as the first embodiment top 1. The operation of top 100 is the same as top 1. A zero has been added to show like parts. Some embodiments of top 100 can be folded into the storage compartment of a Jeep® model.

The number designations for FIGS. 4, 5, and 6 that differ from FIGS. 1, 2, and 3 are listed below:

-   -   110 rear bow     -   90 first linkage arm     -   130 second linkage arm     -   160 K-arm     -   180 second bow arm     -   200 third bow arm     -   210 first bow link     -   220 frame     -   310 front bow     -   320 front clamps     -   250 bow     -   280 bow     -   301 motor support plate flange     -   350 stop     -   370 bracket

Referring next to FIG. 7, the vehicle 174 has a rear tailgate 175 shown without the spare tire assembly. The top 100 is shown fully deployed without the covering material. Wheel wells 7000, 7001 are shown to support brackets 2. The roll bars 700, 701 project nearly vertically from the rear of the rear compartment. They form an approximate right angle at 702, 703 before extending forward to a cross bar 704. This forms a roll cage. Vertical supports 705, 706 are used to support the top's left door bracket 707 and right door bracket 708.

In FIG. 13, the left door bracket 707 is seen to have a side plate roll bar spacer 709 shown in dots to which a bolt 710 is fastened through roll bar mount bracket 711. Roll bar mount bracket 711 is attached to the vertical support 705 with screws 712. The base of left door bracket 707 may have bolts (not shown) fastened to the vehicle body ledge 716. Brackets 707, 708 preferably are made of aluminum and can have mounting flanges readily attached thereto. A rubber gasket 720 seals the air space to the L-arm 1200.

In FIGS. 11 and 12, the L-arm 1200 is shown to have a guide 1210, preferably made of plastic, which forms a groove 1211 to receive the rubber gasket 720 and bracket 707. FIG. 11 shows the left lower bracket 707, and FIG. 12 shows the right door bracket 708 with the top 100 partially closed. The L-arm 1200 pivots at 2 piece T-plate 1216, and a side panel outer guide 1217 helps keep it aligned with the bracket 707. A soft boot 729 slides over door bracket 708. The boot 729 is fitted with a wind sealing rubber gasket 720. These brackets form means for sealing when engaged with the side of the vehicle.

In FIG. 11, the offset steel bracket 33 is pressed against the L-arm 1200 via the first linkage arm 90. FIGS. 8, 9, and 10 show perspective views of the top 100. The windshield 776 has a top rim 777.

Referring next to FIG. 14, the top 100 has a removable rear window 1400. The removable panel 1401 is secured by a zipper 1403 and a hook and loop seam 1402.

Referring next to FIG. 15, the top rim 777 has an inside cutout 778 into which is mounted a custom catch 780 having a base plate 779 with bolts 781. The front clamp 320 is hinged at 321, wherein the user can push upper clip 322 to lock the catch assembly 1500, or pull upper 20 to clip 322 to release the catch assembly 1500. Lower clip 323 engages the catch 780 as shown by arrow E.

Referring next to FIG. 16, a motorless embodiment of top 100 is shown to be identical to the motorized version except that motor support plate flange 3 has no motor. A nut 1600 has replaced gear 8.

Referring next to FIG. 17, the spare tire 170 is shown in solid lines in the factory standard position. In order to accommodate the top 1 shown in FIG. 1, the spare tire must be moved to the position shown by 170 in dots. The rear panel of the vehicle is labeled 175, and the bumper is labeled 174.

Referring next to FIG. 18, features of the top are shown to the top 100 shown in FIG. 4. These features of the top include a rubber seal 3210 attached to the inside lower edge of the front bow 310. A heavy-duty clamp 3206 has been added. Tightening cable 3220 connects to the top 80 by means of a tunnel sewn into the inside of the top. In one alternative, the cable is replaced with a bungee. Cable 3220 pulls the top 80 tight against the linkage members 220, 160. When the top 100 is folded down, the cable 3230 helps prevent the top 80 from wearing against linkage members 200, 290, and 370. A bolt type bow base adjuster 3250 allows adjustment of the bow 110 against the canvas 80. The canvas 80 is one possible means for spanning the supports (linkage arms, etc.). Although canvas is a working solution for the spanning, various other materials, including interlocking substantially rigid panels and other cloth-like materials, may be used.

Referring next to FIG. 19, rear bow adjuster 3255 connects to threaded rod 3251. A sealing gasket 3254 keeps moisture out of the hollow bow tubing 3253. A nut 3252 is connected to the tubing 3253. Turning nut 3252 moves tubing 3253 towards or away from canvas 80.

FIG. 20 shows the vehicle body ledge 716 supporting the anchor 3260. The bow assembly 3280 consists of an anchor 3260 supporting a rod 3261. The tubing 3253 extends over the rod 3261 and ends in a fixed collar 3264. Inside tubing 3253, a spring 3262 is compressed against a stop 3263 as the canvas 80 presses against the bow 110. Thus, assembly 3280 provides a self-adjusting tension mount for bow 110, when the bow is mounted to the vehicle.

Referring next to FIG. 21, a self-adjusting tension mount for bow 250 is labeled assembly 2100. Assembly 2100 consists of a bolt 2101 securing a rod 2103 to linkage 200 by means of a nut 2102. The rod 2103 has a solid end 2105 to compress spring 3262 against stop 3263 when the canvas 80 pushes against bow 250.

Referring next to FIG. 22, the view is taken from inside the vehicle looking out of the left window and seeing canvas 80. The canvas 80 has a tunnel 3290 sewn into the inside left roof line. The cable 3220 is threaded through the tunnel 3290 and anchored at 3225 in tab 2310 of linkage 220 and anchor 3226 at K-arm 160. The cable 3220 tightens the canvas inbound as shown when the top 100 is closed. The cable 3230 keeps the canvas 80 from pinching between linkages 200, 180 in the open position. Anchor 3227 fastens to linkage 200, and anchor 3228 fastens to linkage 290.

Referring next to FIG. 23, the seal 3210 is preferably a rubber gasket glued to the front bow 310 of top 100. The seal 3210 stops air from entering above the windshield top frame 4010, seen in FIG. 24.

Referring next to FIGS. 24-29, the clamp 3200 consists of an anchor 3201 having mounting holes 3202 to enable screws 3203 to secure it in cavity 3204 along the windshield ceiling 3205. Ledge 3206 captures hook 3207 in the locked mode shown in FIGS. 26 and 29. Base 3024 is secured to front bow 310. It has a pivot mount 3023 for handle arm 3022. Handle H is designed to be grabbed by the user's hand.

The handle arm 3022 has a pivot mount 3021 for the hook arm 3020.

FIG. 24 shows the base 3024 having a fastener bolt or rivet 5000 to front bow 310.

FIG. 25 shows the handle H lowered so as to almost engage hook 3207 with ledge 3206.

FIG. 26 shows the hook 3207 engaged with ledge 3206. The user is moving handle H up as shown by arrow UP, thereby locking the clamp. The soft protective cover 4000 is shown in dotted lines. It has a hollow core to fit over the handle H. It has a flap section 4001 which bends with the varying positions of the hook 3207. The back of hook 3207 has a hook and loop member 4002 which removably attaches to hook and loop member 4003 fitted to the forward side of flap section 4001.

FIG. 27 shows the clamp 3200 totally disengaged as if ready for the top to be folded down.

In FIG. 28, the hook 3207 is engaged with the ledge 3206, and the handle H is down, shown by arrow DOWN, so the front bow 310 is not secured against the windshield top frame 4010.

In FIG. 29, the top 100 front bow 310 is locked against the windshield top frame 4010.

Referring to FIGS. 30 and 31, another embodiment retractable top 1000 is seen to have a pair of side mount support plates 301 preferably designed to mount on the side body panel and structural support in the rear compartment of various Jeeps®. A pair of vertical linkage support brackets 3 has a side mount support plate welded or otherwise attached to each of them. These vertical linkage support brackets 3 are one example of a means for attaching the retractable top to the rear compartment. Bolts (not shown) mounted through mounting points 302 and 303 secure the support plates 301 to the vehicle. A parallel vertical trailing arm motor plate 38 supports pivot mount 14. As can be seen in FIG. 31, side mount support plate 301 has holes 302 and 303 for mounting. Support plate 301 includes horizontal plate 304 which contains holes 302. Since support plates 301 are bolted in two planes of motion, additional support and stability is given to the retractable top 1000.

A two-directional motor 7 has a drive gear 71 supported by the support bracket 3, wherein gear 71 drives a linkage gear 8, which is fastened to the first linkage arm 90. The center of linkage gear 8 has an axle 10 which supports first linkage arm 90 in a pivot mount so that first linkage arm 9 can be moved from the fully deployed position shown to the retracted position shown in FIG. 32. A rear bow 110 has a pivot mount 12 so as to fold parallel to the first linkage arm 90 in the retracted position shown in FIG. 3. However, a stop (not shown) stops the bow 110 from moving more than angle a, thereby causing bow 110 to lift and support the canvas top 80 as shown in FIG. 41. Canvas top 80 can be any flexible material. The canvas top is one example of a means for spanning as described above.

A second linkage arm 130 has a pivot mount 14 on the trailing arm motor plate 38. The upper end of second linkage arm 130 has a pivot mount 15 to K-arm 160, which is also pivot mounted at 17 to first linkage arm 90, and has K-arm pistol grip 36 to linkage arm 180. A second bow arm 180 has a pivot mount 19 to third bow arm 200 which has a rear end pivot mounted at 21 to the top of the first linkage arm 90. A first bow link 210 has a pivot mount at a forward end to frame 220 at 23 and a pivot mount 24 to fourth linkage arm 18.

A third bow 250, supported by brackets 370, has a fixed mount bracket 26 to the third bow arm 200. A support rod 270 adds structural rigidity between the two brackets 26. A front bow 280 has a second bow bracket 290 mounted to pivot mount 24. A support rod 30 adds structural rigidity between the two brackets 290. The front bow 310 has windshield clamps 320. During transition, the K-arm 160 continues to move essentially parallel to the ground.

In FIG. 30, the offset steel brackets 33 can be seen extending forward as they are pivot mounted at 34 to first linkage arm 90.

In FIG. 31, the stop 350 is shown midway to flange 36, which prevents the motor 7 from over deploying the top 1000. The motor 7 is a free-wheel type to allow manual deployment of the top 1000, as well as to allow a strong wind to retract the top 1000 when the driver turns the motor 7 off. K-arm control spacer 39 supports linkage arm 18. In FIG. 32, the top 1000 is shown in a further retracted position as compared to FIG. 31 showing how the joints of the top 1000 move in unison.

As described in the previous embodiments, (1, 100) the top 1000 can be completely retracted without changing the spare tire assembly as shown in FIG. 17. Top 1 requires spare tire 170 to be moved to the position shown by dotted lines. Like top 100, top 1000 keeps the spare tire 170 in a factory standard mount shown by solid lines. The rear of the vehicle 174 is numbered 175.

FIG. 33 shows a detail view of one example of how side attachment plate 301 may attach to a vehicle side 5010. This side attachment plate 301 is an example of a means for attaching the top to the rear compartment. Under the lip of vehicle side 5010, a horizontal bottom bar 5015 is bolted to the length of the vehicle side 5015 with bolts 5020. Shims 5025 may be included to distribute the pressure of the attached side attachment plate 301 at the point of attachment and arrange the side attachment plate 301 at the proper height. Further, bottom support bar flange 5026 is configured to provide an attachment point for horizontal plate 304. The side attachment plate 301 extends up to linkage arm 90. Linkage arm 90 connects to offset steel bracket 33 and linkage 5030.

FIG. 34 shows an alternative embodiment that includes linkage 5030. Linkage 5030 is configured to allow for a smooth folding process such that, during folding, L-arm 1200 moves smoothly. Linkage 5030 connects to linkage arm 90 at pivot 34 and to folding L-arm 1200 at pivot 5035. At pivot 34, the connection made by linkage 5025 is a sliding guide. In some alternatives, a protective cover or shroud is included to protect passengers from catching items and skin in the linkages. This protective cover may be made of plastic or other material.

FIG. 35 shows a cross section taken along the cut line shown in FIG. 4. This cross section shows how the top 1000 is attached to vehicle side 5010. As is clear from FIG. 35, bottom support bar flange 5026 extends away from the vehicle side 5010 toward the interior of the vehicle to allow for an attachment point for horizontal plate 301. Shims 5025 allow for the horizontal plate 301 to be mounted at the proper height so that the vehicle side does not interfere with the mounting. Side attachment plate 301 is attached using bolts to bottom support bar flange 5026 through holes 302. Vertical linkage support brackets 3 are connected to horizontal plate 301 using bolts through holes 303.

FIG. 36 shows horizontal bottom bar 5015 and bottom support bar flange 5026 from a top view. FIG. 37 shows the arrangement of horizontal bottom bar 5015 and bottom support bar flange 5026 from a top view and includes shims 5025. FIG. 38 is a cross section taken according to the cut in FIG. 37 and shows the arrangement of the horizontal bottom bar 5015, bottom support bar flange 5026, and shims 5025 from a profile view.

FIG. 39 shows the top 1000 installed without a canvas cover. As is clear, the top 1000 is side mounted (also may be referred to as quarter panel mounted) as opposed to as in FIG. 7 where the top is mounted on the wheel wells. The side mounting allows the top to be configured for usage in vehicles such as the one shown in FIG. 39, where the wheel wells are not flat or where the floor or other flat surface for mounting is not available. In FIG. 39, the floor or wheel well is not available for mounting and, therefore, the side mounting configuration is needed.

As shown in FIG. 40, the side mount may be used in any vehicle, not just those where floor or wheel well access is unavailable. FIG. 40 shares many similar parts as described in relation to FIG. 7, and like numbers represent similar parts. In addition, roll cage bracket mount 5050 is shown. Roll cage bracket mount 5050 includes two cage bar attachment points, rear attachment point 5055, and front attachment point 5060. Additional detail related to roll cage bracket mount 5050 is shown below in relation to FIGS. 62 and 63. Roll cage bracket mount 5050 can eliminate the need for side attachment to the vehicle.

Referring next to FIG. 40, the vehicle 174 has a rear tailgate 175 shown without the spare tire assembly. The top 1000 is shown fully deployed without the canvas. Instead of the top 1000 being attached to wheel wells 7000 and 7001, the top 1000 is attached to the side of vehicle 174 using the roll cage bracket mount 5050 and the vehicle 174 side. The roll bars 700, 701 project nearly vertically from the rear of the rear compartment. They form an approximate right angle at 702, 703 before extending forward to a cross bar 704. Vertical supports 705, 706 are used to support the top's left door bracket 707 and right door bracket 708.

FIGS. 41, 42, and 43 show perspective views of the top 1000: a rear perspective, a front perspective, and with the top refracted. FIGS. 44 and 45 further show detailed views of the arrangement of the L-arm 1200 and its position in retracted and up positions. FIGS. 44 and 45 generally correspond to FIGS. 11 and 12.

In FIG. 46, the left door bracket 707 is seen to have a side plate roll bar spacer 709 shown in dots to which a bolt 710 is fastened through roll bar mount bracket 711. Roll bar mount bracket 711 is attached to the vertical support 705 with screws 712. The base of left door bracket 707 may have bolts (not shown) fastened to the vehicle body ledge 716. Brackets 707, 708 are preferably made of aluminum and can have mounting flanges readily attached thereto. A rubber gasket 720 seals the air space to the L-arm 1200. The L-arm 1200 is configured to function in conjunction with side panel outer side panel outer guide 1217, side panel inner guide 1215 and sealing bracket base bar 5045 to support and position top 1000 when it is in an up position.

Referring next to FIG. 47, the top 1000 has a removable rear window 1400. The removable panel 1401 is secured by a zipper 1403 and a hook and loop seam 1402.

FIG. 48 shows the gear arrangement for a motorized version of top 1000. Top 1000 may be configured to be manually raised and lowered, such as shown in FIG. 16 in relation to previous embodiments. As shown in the embodiments depicted, top 1000 may include a motor 7. Attached to motor 7 is bevel gear 5071 which is configured to interface with bevel gear 5070. A variety of gearing may alternatively be used including worm gears, etc. Motor 7 and bevel gear 5071 are mounted into gear box 70. Gear plate 5074, which includes bevel gear 5070, is also mounted into gear box 70 using bolts 5072.

FIG. 49 shows the arrangement of gear box 70 and motor 7 with axle 5073 and linkage arm 90. Gear 71 is interconnected with gear 5070 and mounted in gear plate 5074. Gear 71 is oriented in motor support plate flange 3 such that it interfaces with gear 8. Gear 8 is mounted on axle 5073 and turns in response to the movement of gear 71 causing top 1000 (or when implemented in other embodiments, top 1 or top 100) to extend or retract. Gear 8 is bolted to linkage arm 90 such that, when it pivots, linkage arm 90 similarly pivots.

Referring next to FIG. 50, features of the top are shown to the top 1000. These features of the top include a rubber seal 3210 attached to the inside lower edge of the front bow 310. A heavy-duty clamp 3206 has been added. Tightening cable 3220 connects to the canvas top 80 by means of a tunnel sewn into the inside of the canvas. Cable 3220 pulls the canvas 80 tight against the linkage members 220, 160. When the top 1000 is folded down, the cable 3230 helps prevent the canvas 80 from wearing against linkage members 200, 290, and 370. A bolt type bow base adjuster 3250 allows adjustment of the bow 110 against the canvas 80.

Referring next to FIG. 51, rear bow adjuster 3255 connects to threaded rod 3251. A sealing gasket 3254 keeps moisture out of the hollow bow tubing 3253. A nut 3252 is connected to the tubing 3253. Turning nut 3252 moves tubing 3253 towards or away from canvas 80.

Referring next to FIG. 52, a self-adjusting tension mount for bow 250 is labeled assembly 2100. Assembly 2100 consists of a bolt 2101 securing a rod 2103 to third bow arm 200 by means of a nut 2102. The rod 2103 has a solid end 2105 to compress spring 3262 against stop 3263 when the canvas 80 pushes against bow 250.

FIG. 53 shows the vehicle body ledge 716 supporting the anchor 3260. The bow assembly 3280 consists of an anchor 3260 supporting a rod 3261. The tubing 3253 extends over the rod 3261 and ends in a fixed collar 3264. Inside the tubing 3253, a spring 3262 is compressed against a stop 3263 as the canvas 80 presses against the bow 110. Thus, assembly 3280 provides a self-adjusting tension mount for bow 110 when the bow is mounted to the vehicle.

Referring next to FIG. 54, the view is taken from inside the vehicle looking out of the left window and seeing canvas 80. The canvas 80 has a tunnel 3290 sewn into the inside left roof line. The cable 3220 is threaded through the tunnel 3290 and anchored at 3225 in tab 2310 of linkage 220 and anchor 3226 at K-arm 160. The cable 3220 tightens the canvas inbound as shown when the top 1000 is closed. The cable 3230 keeps the canvas 80 from pinching between linkages 200, 180 in the open position. Anchor 3227 fastens to third bow arm 200, and anchor 3228 fastens to linkage 290. In one alternative, the rigidity of the cable is such that when the top folds down the cable tends to bow out away from the linkage bows and arms. This tends to prevent the pinching and tearing of the enclosure material.

Referring next to FIG. 55, the seal 3210 is preferably a rubber gasket glued to the front bow 310 of top 1000. The seal 3210 stops air from entering above the windshield top frame 4010, seen in FIG. 24.

Referring next to FIGS. 56-61, a similar clamp to that shown in FIGS. 24-29 is shown. The clamp 5100 consists of an anchor 5110 having mounting holes 5111 to enable screws 5112 to secure it in cavity 5115 along the windshield ceiling 5116. Ledge 5120 captures hook 5125 in the locked mode shown in FIGS. 58 and 61. Base 5126 is secured to front bow 310. It has a pivot mount 5127 for handle arm 5128. Handle 5129 is designed to be grabbed by the user's hand. The handle arm 5128 has a pivot mount 5130 for the hook arm 5131 which is attached to hook 5125. FIG. 56 shows the base 5126 having a fastener bolt or rivet 5000 attached to front bow 310. FIG. 57 shows the handle 5129 lowered so as to almost engage hook 5125 with ledge 5120.

FIG. 58 shows the hook 5125 engaged with ledge 5120. The user is moving handle 5129 up as shown by arrow UP, thereby locking the clamp. The soft protective cover 4000 is shown in dotted lines. It has a hollow core to fit over the handle 5129. It has a flap section 4001 which bends with the varying positions of the hook 5125. The back of hook 5125 has a hook and loop member 4002 which removably attaches to hook and loop member 4003 fitted to the forward side of flap section 4001.

FIG. 59 shows the clamp 5100 totally disengaged as if ready for the top to be folded down. In FIG. 60, the hook 5125 is engaged with the ledge 5120, and the handle 5129 is down, so the front bow 310 is not secured against the windshield top frame 4010. In FIG. 61, the top 1000 front bow 310 is locked against the windshield top frame 4010.

Referring back to FIGS. 30 and 31 in one embodiment linkages 180, 200 are configured slightly differently to provide increased performance. In FIG. 64 an alternative to linkage 180 is shown, referred to here as second bow arm 6480. Second bow arm 6480 includes tapered interconnection apertures 6481, 6482, 6483. These apertures are tapered in order to recess the attachment mechanism used, in this case a bolt. As is clear from FIG. 30 the second bow arm 6480 (replacing linkage 180) must interface with first bow arm 210, a third bow arm 200, and a K-arm 160. The tapering of the holes to recess the bolt allows the third bow arm 200 to pass the linkage point for the first bow arm 210 without catching on a linkage that protrudes. Furthermore, since the tapered interconnection aperture 6483 is located in a position so that first bow arm 210 will sit higher than the connector to the pivot connector 290, the retractable top will tend to have a flatter profile when extended. Third bow arm 200 has also been adjusted accordingly. Aperture 6484 provides for a different placement of the cable shown in FIG. 54. In FIG. 54, the cable terminates at connection point 3228. If the second bow arm 6480 is used, the cable terminates at aperture 6484. In FIG. 65 an alternative to a third bow arm 6610 is shown with spacer 6630. Shown in FIG. 66, by adjusting third bow arm 6610 to have a diagonal arrangement of connection apertures 6620, 6625 for second bow bracket 290, the retractable top also tends to have a lower profile.

Additionally, FIG. 67 shows an additional embodiment of a L-arm 1200. Sealing bracket 6710 is similar to L-arm 1200 but additionally includes slot 6715 which allows the sealing bracket 6710 to slide into place by allowing for vertical movement.

In FIGS. 68 and 69 a and 69 b an alternative mounting arrangement is shown. In some embodiments, if the mounting plates for the retractable top have any angular movement, the interface of the retractable top will be significantly off. In order to combat the movement of the mounting plates, vertical linkage support plate 3 and motor support plate flange 301 may be replaced with the inner motor support plate 6810 shown in FIG. 68 and the outer motor support plate 6910 shown in FIGS. 69 a and 69 b. The inner motor support plate 6810 includes six slots providing for rotational stabilization of the support plate 6810 while allowing for forward and backward adjustment of the spacing of the support plate 6810. The four peg slots 6825 receive a circular peg which is the width of the slot 6825. The bolt slots 6815, 6820 receive bolts for tightening the support plate in place. The combination of the pegs in the four peg slots 6825 significantly lessens any possible angular movement of the support plate. The support plate interfaces with outer motor support plate 6910. Outer motor support plate 6910 includes 4 bolts holes 6915, 6920 and four pegs 6925. The pegs 6925 interface with the peg slots 6825 and the bolts (not shown) that run through the 4 bolts holes 6915, 6920, interface with the two bolts slots 6815, 6820.

Referring next to FIGS. 70-72, a similar clamp to that shown in FIGS. 56-61 is shown. The clamp 7000 consists of an anchor 7010 having mounting holes 7011 to enable screws 7012 to secure it in cavity 7015 along the windshield ceiling 7016. Ledge 7020 captures hook 7025 in the locked mode shown in FIG. 72. Ledge 7020 is angled down and towards the front of the vehicle in order to provide locking leverage. Base 7026 is secured to front bow 310. It has a pivot mount 7027 for handle arm 7028. Handle 7029 is designed to be grabbed by the user's hand and is lengthened as compared to handle 5926. The handle arm 7028 has a pivot mount 7030 for hook 7025. Compared to the clamp of FIG. 58 the number of elements has been reduced by combining the hook and hook arm. FIG. 72 shows the hook 7025 engaged with ledge 7020.

The foregoing description of the embodiments of the retractable top systems and methods has been presented only for the purpose of illustration and description and is not intended to be exhaustive or to limited to the precise forms disclosed. Numerous modifications and adaptations are apparent to those skilled in the art without departing from the spirit and scope of this disclosure.
